66 REVISION OP THE AMYCTERIDES, vi., 



small spines about declivity on third and fifth interstices and one or two about 

 shoulder. Intermediate tibiae notched. 



Hub. — Western Australia: Nicoll Bay. 



In my collection are two females which have been compared with the type, on 

 which a more detailed description has been based. 



2. Moderately densely clothed with small sandy squames, maculate on elytra 

 with larger white scjuames and with white vittae along inner sides of the second 

 and third rows of tubercles; sides extensively clothed with white squames and 

 vittate along lower border. Rostrum shallowly excavate, sides obtusely angidate 

 in front. Head with raised intercristal ridge, supraorbital crests widely separated, 

 consisting of a single, upward, and slightly backwardly directed spine with a 

 short, spicule-like, anterior ramus. Antennae with fii-st joint of funicle longer 

 than second, and both rather short. Protliorax with the median tubercles on each 

 side small, hardly conical, not in a straight line, the central ones more outwardly 

 placed ; median area raised with a few scattered granules ; lateral margins with a 

 spiniform tubercle in front of middle, with a small one at base, anteriorly; pos- 

 terior lateral tubercle reduced to a small granide. Elj'tra with tubercles much 

 reduced in size, on greater portion of interstices mere granules, hardly distinguish- 

 able from the granules of the other alternate interstices ; first row with only 2 — 3 

 spines posteriorly, the penultimate the largest; second row with 4 posteriorly; 

 third with small humeral and smaller infrahumeral tubercles, the rest mere 

 granules. Venter ratlier densely clothed with yellow decumbent setae, and 

 with white squames at sides, apical segment not strigose. Dimetis-ions: 2. 15 x 6 

 mm. 



Hab. — Western Australia: Condon (H. M. Gdes). 



This species can be readily separated from it.s congeners, ,1. tragoeephalus 

 and allies, by the prothoracie tubercles being smaller and the central ones more 

 outwardly placed. According to my notes, the male has the middle tibiae notched 

 subapicaUy, though the other species of the tatei group have the tibiae simple.

c?. Rather small; black, more or less densely clothed witli brown subpubes- 

 cence, maculate with grey. 



Head concave in front, obliquely and rather indistinctly longitudinally ru- 

 gose, with two obscure gi-anides, sometimes absent, about middle; head separated 

 from rostrum above by a transvei-se groove; supraorbital crests single, projecting 

 upwards and pointed at apex. Rostrum concave above, with a distinct median 

 carina; external margins moderately raised, with a distinct tubercle anteriorly; 

 internal ridges slightly raised. Antennae with scape distinctly curved, somewhat 

 bisinuate; funicle with second joint mucli longer than fii-st; club elongate, pedun- 

 culate. Protliorax flattened or feebly concave; anterior margin subtruncate, not 

 produced over head, ocular lobes absent ; disc closely set with granules, the sub- 

 median tubercles hardly distinct from the granules; lateral tubercles strong, tri- 

 anguliform, the median the largest, the anterior tubercle somewhat smaller, eon- 

 joined with median at base, the posterior tubercle smaller than median, acute, 

 with a small tubercle at base anteriorly, and a granule posteriorly. Elytra emar- 

 ginate and separately muei-onate at apex; with rows of evident punctures and
